IMPROVED MUD BOAT.

TO ALL WHCM IT MAY CONCERN: i

Be it known that I, ALMON D. INIANLEY, of Washington, Macomb county,State of Michigan, have invented a new and useful improvement in MudBoats; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawing, forming a partof this specification, in whichi 'Figure I is avertical cross-section of my improved mud boat, taken through the-line:l: rv, fig. 2.

Figure 2 is a vertical longitudinal section of the same, taken throughthe line yy, iig. 1.

Similar letters of reference indicate like parts.

My invention has for its object to furnish an improved mud boat, soconstructed and arranged that the mud may be conveniently dumped throughthe bottom of the b oat when transported to the desired place; and itconsists, first, in the combination of one or more mud vats with twoboats, placed parallel with each other, and connected with timbers; andsecond, in the combination of" sectional drop bottoms and a lever-catchwith the mud vats, where said drop-bottoms are constructed and arrangedsubstantially as hereinafter more fully described.

A are the supporting boats or huoys, which are made with tight, smoothdecks, and may have flat or curved ttoms, as'may be desired. These boatsA are placed at a suitable distance apart, and parallel to each other,andnare connected together by planks or timbers B, of suiicient strengthto `support the mud vats and their contents. C are the mud rats', one ormore of which are placed over the opening between the boats or buoys A.rIhese vats may be placed across said opening or space, or longitudinaltherewith, Yas may be desired. But I prefer to place them across saidvats, as increasing the carrying capacity of the said vats. The sectionsc1 and c2 of the bottoms of the vats are securely attached to therollers D, which support them, and the ends of which are pivotcd to theconnecting timbers B, orto the boats A, according as the vats C areplaced across or longitudinally with the opening between the said boatsA. 'The edges of the sections cI a d c2 that'come in contact with eachother are inclined or bevelled, as shown in figs. I and 2, so that theone section e may support the other, as shown. The ends c3 and c of thevats C are securely attached to the sections e and c2 of their bottoms,as shown; and said ends have shoulders formed upon their outer sides,upon which the lever-catch E takes hold and holds the said bottomsclosed. Tho-sections or parts cI and c2 of the bottoms ot' the vats Cmay bc made of different lengths. And one or both parts should be sohung upon the rollers D that as soon as thev catch-lever E is drawn backthe weight of the load will overbalance them, discharging the loadbetween the boats or buoys A. The lower ends of the levers E are pivotedto the timbers of the boats A, or to the connecting timbers B, accordingas the vats C are placed longitudinally with or across the space oropening between the said boats A. Upon the sides of the levers E areformed shoulders, which take hold of the shoulders formed upon the endboards c3 ot'l the vats C, and hold the said bottoms c and c2 securelyin place.

`I claim as new, and desire to secure by Letters Patent:

1. The combination of one or more mud vats C with two boats or buoys A,placed parallel with each other, and connected with timbers B,substantially as herein described, and for the purpose set forth.

2. The combination of the sectional drop-bottoms cl c2 and thelever-catch E with the mud vats C, when the said drop-bottoms areconstructed and arranged substantially as hereindescribed and for thepurpose set forth.

The above specification of my invention signed by me this 16th day ofJuly, 18.66. Y
